# == Class: ::midonet::cassandra
#
# Install and run the cassandra component
#
# === Parameters
#
#  [*seeds*]
#    Full list of cassandra seeds that belong to a cluster.
#  [*seed_address*]
#    IP address to bind for this instance. (Must belong to the
#    seeders list.
#  [*storage_port*]
#    Inter-node cluster communication port (defaulted to 7000).
#  [*ssl_storage_port*]
#    SSL Inter-node cluster communication port (defaulted to 7001).
#  [*client_port*]
#    Cassandra client port (defaulted to 9042).
#  [*client_port_thrift*]
#    Cassandra client port thrift (defaulted to 9160).
#
#
# === Examples
#
# * The easiest way to run the class is:
#
#       include ::cassandra
#
#   And a cassandra single-machine cluster will be installed, binding the
#   'localhost' address.
#
# * Run a single-machine cluster but binding a hostname or another address
#   would be:
#
#        class {'::midonet::cassandra':
#            seeds              => ['192.168.2.2'],
#            seed_address       => '192.168.2.2',
#            storage_port       => 7000,
#            ssl_storage_port   => 7001,
#            client_port        => 9042,
#            client_port_thrift => 9042,
#        }
#
# *  All the ports must be configured the same in all the nodes in the cluster.
#
# * For cluster of nodes, use the same 'seeds' value, but change the
#   seed_address of each node:
#
# - On node1
#        class {'::midonet::cassandra':
#            seeds              => ['node_1', 'node_2', 'node_3'],
#            seed_address       => 'node_1'
#            storage_port       => 7000,
#            ssl_storage_port   => 7001,
#            client_port        => 9042,
#            client_port_thrift => 9042,
#        }
# - On node2
#        class {'::midonet::cassandra':
#            seeds              => ['node_1', 'node_2', 'node_3'],
#            seed_address       => 'node_2'
#            storage_port       => 7000,
#            ssl_storage_port   => 7001,
#            client_port        => 9042,
#            client_port_thrift => 9042,
#        }
# - On node3
#        class {'::midonet::cassandra':
#            seeds              => ['node_1', 'node_2', 'node_3'],
#            seed_address       => 'node_3'
#            storage_port       => 7000,
#            ssl_storage_port   => 7001,
#            client_port        => 9042,
#            client_port_thrift => 9042,
#        }
#
# NOTE: node_X can be either hostnames or ip addresses
# You can alternatively use the Hiera.yaml style:
#
#     ::midonet::cassandra::seeds:
#         - node_1
#         - node_2
#         - node_3
#     ::midonet::cassandra::seed_address: 'node_1'
